ByDesign Intake Manifold 991 Turbo/turbo S

The By Design intake manifold for the Porsche 991 turbo is machined from a block of billet aluminum.  It replaces the factory Porsche plastic intake manifold that will break on high horsepower cars.  The plastic intake manifold is prone to big leaks when running high boost.  They often split at the seems causing an issue that is often difficult to identify.  At other times the plastic intake is blown to pieces, this problem is easy to identify when it happens.

It offers more airflow and is the only option when making big horsepower and using a port injected fuel system like a Motec or Syvecs ECU. Already made for aftermarket injectors this manifold will make that tricky part of the job easy.
